Number of the sensor's measurement points, shown to the catalog's scale.
The largest sensor in the database has 327 680 points.
Published by the manufacturer
MODEL DISCONTINUED AT FLIR ('Discontinued' on the manufacturer's page), but still actively sold by numerous professional distributors with no mention of its discontinued status, exactly like the already-covered TG267 in this catalog.
Restricted distribution. At least one retailer states delivery limited to the United States, Canada, and Puerto Rico — a case of geographic restriction already seen with the Fluke Ti401 PRO and the FLIR ONE Edge Pro.

Observations
The widest measurement range in the entire database at the high-temperature end. Up to 1030°C, thanks to a dedicated optical filter, versus 650°C for the best professional devices in this comparison. Designed for glass furnaces, industrial ovens, and forges — a use case entirely absent from the rest of the database.
Remarkable accuracy for a device in this segment. ±1.5°C between 50 and 100°C, versus generally ±2°C or more on the other imaging thermometers in the database.
A 30:1 distance-to-spot ratio, the best of the three FLIR TG models in the catalog (24:1 for the TG267 and the TG165-X).
Emissivity limited to four presets plus a custom setting, while most professional devices in this comparison offer continuous adjustment from 0.01 to 1.00.
Neither accuracy above 100°C, nor NETD conditions, nor a verified vertical field of view, nor full radiometry are documented.
